In a world reminiscent of the early modern period, where war is fought with line infantry, I, the protagonist, have been reborn. As a commoner second lieutenant, I am ostracized as "Death," and assigned as a staff officer to the 6th Special Task Force, which consists entirely of women. The regiment commander, who seems to be plotting something, the easy-going non-commissioned officers, and the soldiers, who are all amateur girls, are all women. If things continue as they are, everyone may die in battle. I have to do something... but how?! ※ Serialization period: April 11, 2021 - April 28, 2023 (Sequels and side stories are being serialized irregularly)
